Sorry to hear that this problem is recurring, I thought it had been sorted. Why anyone would want to volantarily fly holds is beyond me; we get enough practise at LHR as it is!
I think the reason why people take the delay in the air rather than on the ground is down to human nature. i.e the punters.
Passengers don't like sitting on the ground at their destination airport and are prone to get aggitated and act even more stupidly than normal.
I think these guys doing loops over the Surrey countryside are just taking the easy option.
